Thank you for finally posting in the forum about your problem. This is the place to ask questions for these types of things, not in every article.

Would you be able to specify the internet problem that you are having, like does it keep on dropping for example? I doubt that downgrading is the solution. Also, you may be next in line for a new upgrade to Android 4.4.3 that could help fix this, if it happens to be a bug.

Hello there, the problem I am having is when am using the mobile Internet it takes a very long time to open the page, sometimes it doesn't it says error. When am using the wi Fi though it works very well. Before I update, it was working very well on 4.2.2. Any solution. Thanks
